First,it has many advantages, such as （例如说有那些优点,或者
对什么有什么好处等）.
Also, it has many disadvantages (例如说有那些缺点,或者对什么有什么坏处等）.
In a word, xx just like a double-edged sword, both have good effect and bad influence. So we have to look at it rationally, try to make good use of it and avoid it's disadvantage.
这样套写大部分都可以用,要加的东西要写的好,理由充分的话得个七八成分应该问题不大.
这些已经有7,8十字了,再加上话题换过来,后面的各写20个左右的单词,四级作文字数就绰绰有余了,六级的就要求再高点,后面的写,2,30个左右,也就列举个2,3条理由,这样字数也超过了
当然上面说的有些也可以替换,不过基本结构思路都差不多了.
